Tunable electrocaloric effect in lead scandium tantalate through calcium doping
Youri Nouchokgwe, Natalya S. Fedorova, Pranab Biswas +11
State-of-the-art electrocaloric cooling prototypes rely on the conventional electrocaloric effect of ferroelectric lead scandium tantalate (PbSc0.5Ta0.5O3, PST), which peaks near r…

Quantitative correlation between structural (dis-)order and diffuseness of phase transition in lead scandium tantalate
T. Granzow, A. Aravindhan, Y. Nouchokgwe +9
Ferroelectrics show a phase transition to a paraelectric phase at a well-defined transition temperature. Introducing disorder makes this transition diffuse, and the system becomes…
